SPECIFICATION forming part of Letters Patent No. 786,996, dated April 11, 1906.

Application tiled October To all whom it ntwy concern:

' Be it known that Iv KNIeH'r E. ROGERS, a

citizen of the United States, residing at South Manchestelgin thecounty of Hartford and 7 machines, has for its object the production of anovel machine wherein an endless wire belt or gauge is made totravel over a non-rotatlve suction-box having its perforated face immersed in the pulp in the vat, the water holding the pulp in suspension being drawn into the box, theincoming water passing also through the woven-wire belt or gauze, the fibers in the pulp being directly deposited on the belt or gauze, the fibers sucked onto the wire belt or gauze from the pulp, which is kept well chu rned or agitated, being crossed or matted together, thus insuring the production of a strong web which maybe varied in thickness through controlling the intensity of the vacuum-creating "means coacting with the suction-box to exhaust'the same, variations in the intensity of the vacuum causing the fibers of the pulp v qontained in a pulp-vat.

to be deposited more or less rapidly on the wire belt. Variations in thickness of the web of paper may also be efliected by changing the speed of the wire belt or gauze across the non-rotative suction-box in.the pulp. The

wire belt has coacting'with it an apron, pref- .the pulp-sheet Prior to my invention no part of a non-rotative'suctlon-box over whleh a wire belt is made totravel has ever been Immersed 1n pulp of the non-rotative suction-box in the pulp in the .vat and keepingthe pulp stirred it is not only possible to make stronger paper when .-thus laying the fibers of the pulp, floating in every direction, across each other, and thus in- I sure the formation of a very closely-matted web, butit is also' possible to deposit more or less of the fibers of the pulp and deliver from one wire belt'a homogeneous web ofany desired thickness.

Prior to vmy invention heavy webs for pay locating a part 6,1904. Serial No. 227,402.

tease, have been madeby the-employment of a plurality of cylinder-molds, each located in its own pulp-vat, the webs formed on the separate cylinder-molds being brought in contact and united by-pressure, &c., thus making a thick web of a plurality of thin plies, the thick web so produced presenting alami' nated structure which is not [so-strong as a homogeneous web, such as may be made by the apparatus herein described as being formed by depositing fibers on one wire belt or gaune. My invention therefore comprises, broadly,

a vat to contain pulp, a non-rotative suctionbox sustained in the pulp, and a movable and less wire belt or gauze on which the pulp may be deposited by exhausting the suctionwbox. Other features of my invention willbe here'- inafter more fully set forth in the end of this specification.

Referring to the drawings, Figure 1 represents a paper-making machine in which the fibers of the pulp embodying my invention are shown in one good form. Fig. 1" shows the claims at my novel suction-box with deckles applied thereto to control the width of the pulp-web and of the paper; and Fig. Zrepresentsa mawirebelt or gauze and the felt or apron being somewhat diflerently arranged one withflrelation to the other.

The vat 1, Fig. 1, receives in usual manner thin liquid 9 u'lp composed of'water and fibers of any consistency.

The vat contains a roll 6, located near the '75 I chine embodying my invention, the endless bon g moved spend of ODLLM. on

It will be understood that the suction-box is movably is of the thickness desired I determinethe sustained in any suitable manner within the pulp-vat.

Instead of applying, as above stated, one layer of pulp on another layer until the paper thickness of the'paper by depositing the same as asingle web of the required thickness, and i in doing this the inclination of the face-of the.

suction-box over which the endless wire-gauze belt is moved is of very decided importance for the reason that the part of. the wire-gauze belt first to'receive the pulp is immersed deeper-in the stuff or liquid pulp in the vet amount of fiber held in suspension in the liqor liquid pulp we're less than shown.

than if the face of the suction-box occupied a position :-in a horizontal plane, and conse: quentlythe vacuum-.orsuction in the box is enabled to start toward the belt a greater uid pulp than as though the depth of the stuff Hence the inclination of the, suction-box becomes a matter of great importance.
